This has been a very active page with suggestions about the science and replications. Ideas about using large-piston compressor that runs from the chain speed about ways to get water to flow with floats to reduce drag about how to increase the "heat pump" effect contribution and efficiency.

Plexiglas Demo at Autumn Fair 2014

Here's a video showing them demonstrating their Plexiglas see-through version at a trade show by Adolf Schneider in Breganz, Switzerland, October 18, 2014. It shows the inner workings of how the compressed air fitting lines up with the rotating floats. Note that the apparatus is on wheels, which rules out hidden wires from under the device.

(The April 25 - May 6, 2015 demo will not be Plexiglas, as it is a production prototype for what will be installed for kit sales for the production of power.)
